Explanation:

Biochemical reactions are reactions that occur within the bodies and cells of living organisms. Biochemical reactions involve catabolism and anabolism which together are known as metabolism. Thus, biochemical reactions are metabolic reactions which involve either breaking down of large complex molecules into simpler molecules or joining of small molecules to form large molecules. These reactions occur with the help of enzymes which are protein in nature and involve carbohydrates, fats, proteins, nucleic acids and other biological molecules. Pharmaceutical reactions are reactions and interactions of pharmaceutical drugs with the body. It is used by healthcare professionals to find the effectiveness of a drug to cure any disease or disorder. Pharmaceutical drugs usually have specific receptors on them which interact with molecules of the body and cause change in the response of an organism. These reactions can also be called pharmaceutical drug reactions. Two drugs can also interact with each other to decrease or increase effectiveness of each other. Diagnostic chemical reactions are used in healthcare industry to diagnose any disease. Diagnostic reagents are an important component of these types of reactions
